Three Ways to Hand 4,000 Lines of Logs to an Agent — Paste, .txt Attachment, or @ Reference
v2.3.0 added plain-text attachments, which means there are now three ways to hand a long log to an agent — and a new question about which one to pick. Here is how I trim, measure, and decide, with the scripts I actually run.
Tracing What a Long Agent Run Actually Did: Review That Starts From In-Conversation Search
How to use the in-conversation search added in Antigravity v2.1.4 as the starting point for reviewing long agent runs. Choosing search terms, the decision points to inspect, and reconciling with background-agent logs, with concrete steps.
Tracing Parallel Agents After the Fact: Observability with Structured Logs and Spans
Running multiple agents in parallel on the Antigravity 2.0 desktop makes it impossible to tell which one is doing what. I share an observability design that drops tangled print debugging for run_ids and spans you can trace afterward, with a solo-operator implementation and numbers.
Record & Replay for Antigravity Agents — A Production Pattern to Reproduce Failures in 3 Minutes
How to deterministically replay a failed Antigravity Agent run offline, drawn from a month of running it across four production sites. Covers boundary recording, R2 + KV storage costs, PII masking, and a working TypeScript harness.
Wiring Antigravity 2.0 to Chrome DevTools for agents 1.0: Lighthouse Audits, Extension Debugging, Memory Hunts, and an Operational Plan
Chrome DevTools for agents 1.0 went stable and now ships bundled with Antigravity 2.0. Here is the practical setup I run across my 50M-download indie app business: Lighthouse audits, extension QA, memory leak triage, and auto-connect rules.
RecyclerView IndexOutOfBoundsException: The Defensive Copy Fix Antigravity Initially Missed
After 50+ RecyclerView crashes appeared in 28 days post-release, here's how I used Antigravity to debug the issue — and why the first suggestion missed the real cause.
Debugging in the AI Agent Era — When to Trust and When to Question
Working with AI agents fundamentally changes how you debug. The question of 'where do I look first?' has shifted — and staying stuck in old habits means getting stuck in new ways. Here's how to recalibrate.
Replay-Driven Agent Design — Time-Travel Debugging for Production AI Agents
Reproduce one-off agent failures from production on your laptop. A practical three-layer replay design — event, state, and decision — built on top of Antigravity's Manager Surface, with TypeScript code you can drop into your own stack.
Retry Isn't Always the Answer in Antigravity — How to Tell When to Retry vs. When to Rethink
Learn when to use Antigravity's Retry feature and when it's time to change your approach entirely. A practical guide to diagnosing root causes before burning time on repeated failed attempts.
Pairing git bisect with Antigravity's AI to Find a Regression's Root Commit in Minutes
When something worked last week and is broken today, git bisect plus Antigravity's AI can isolate the offending commit in under thirty minutes. Here is the working split between human and AI that I have found most reliable.
Antigravity Retry Stuck in a Loop? A Triage Guide That Actually Breaks It
Pressing retry in Antigravity feels like it should eventually work, but sometimes the same failure keeps coming back with only tiny variations. This guide names the three modes the retry loop falls into, walks through a triage flow, and gives you a rule of thumb for when to stop retrying and start intervening.
Diagnosing and Stopping Runaway Agent Loops in Antigravity
Build agents with Antigravity and you will eventually meet the 'same tool called twenty times in a row' problem. Here is how to classify the failure mode and stop it at the implementation level.
